Generally, only the global horizontal radiation data are available. To calculate a tilted global radiation, it is necessary to estimate the diffuse or the direct component of the horizontal solar radiation. In this article, a statistical procedure has been employed to develop correlations between the hourly measured of global radiation on horizontal surface and its diffuse component. In this context, the present work compares nine models for estimating diffuse fraction, using a 10 years data archive (1996–2005) of hourly global and diffuse solar radiation obtained at Tamanrasset meteorological station. After a first comparison of these nine models, three better performing models were selected for a more detailed analysis. The accuracy of the candidate correlations are performed in terms of the two widely used statistical indicators, MBE, RMSE and t-stat was also introduced. Thereby, new correlation coefficients are established taking into account the local data. The results suggest that some models can improve more accurately, by calibration procedure, the performance of the predictive models.","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130000966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The precursor concentration effect on structural, optical and electrical properties was examined. The X-ray Diffraction (XRD) characterization shows the formation of single tetragonal rutile phase with (110) plan as preferential orientation. Excellent high transmittance greater than 97% in visible was measured by Ultraviolet-visible spectroscopy (UV-Vis). The presence of the interference fringes reflects that the obtained films are thick enough. The results reveal that increasing in precursor concentration leads peak intensity (110), particle size, film thickness and absorbance to increase as well. While the optical transmittance decrease when increasing the precursor concentration.","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132839756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method features a variable step iteration of duty ratio in order to get over the trade-off between dynamic performance and steady state oscillation around maximum power point (MPP). This is done through an MPP pass-through detection α and an acceleration mechanism β. Besides, a full stability test of the DC-DC power converter transfer functions is carried out using the Z-transform and has shown satisfactory results. Moreover, and since partially shaded series-connected PV modules exhibit multiple power maxima due to their integrated bypass diodes, all the centralized MPP trackers with all the available optimizations cannot harvest the max power delivered by the total PV sources and hence, are considered as non cost-effective. From that point on, the authors propose a distributed architecture driven by an intelligent α − β MPPT-based algorithm.","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130944187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the self-consumption present constraints related to variations in the solar production and the load curve of the consumer. In order to promote the use of renewable energies, contribute to the reduction of gas CO2 emissions, protect the environment and ensure sustainable development, FSTS has chosen to install a photovoltaic system in self-consumption. The aim of this work is to present an approach and strategy to find the optimal power of a PV station, adapted to the energy needs of the FSTS, generating the most producible and less spending. A technical-financial study show the feasibility of installing a PV station of optimal power of 200 kWp with a return on investment of 8 and a half years, and a surplus of 30% of solar energy produced annually, the management of this surplus could further reduce the point of profitability of this project.","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134434816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that the convection heat transfer coefficient increased with the suspension of the nanoparticles.

Heat transfer through the components of PV/T collector, taking into account energy losses by conduction, convection and radiation, are implemented by numerical simulation. The knowledge and control of the temperature in each point of the PV panel are important and permit to limit at best the temperature gradients across its surface.

Perturb and observe (P&O) algorithm is used to extract the maximum power from PV and Tip speed ratio (TSR) controller for the WECS. The dynamic behavior of the proposed HPS is examined under different conditions based on wind speed variation and solar radiations. The BDG is involved only for backup when the battery state of charge (SOC) is less than 45%. A Hysteresis technique is used to control the BDG startup on based on the variation of the battery SOC. The developed HPS consists of a 50 W photovoltaic panel, 300 W wind turbine, 400 W biodiesel generator and 200 Ah/24 V battery.

This paper presents modeling and optimization of the distillation column of NGL fractions, especially the deethanizer and depropanizer columns. The calculation of the NGL separation columns was performed by using Peng-Robinson thermodynamic model, with the help of Pro II software. A technical feasibility study was followed to run the NGL separation columns at optimum values of pressure and reflux ratio to optimize efficiency of the column. The results allowed us to highlight the effect of these parameters on the energy efficiency of the NGL separation columns. From an economic point of view, separate the NGL with optimal parameters may contribute to a decrease in expenses related to the energy consumption and CO2 emission.","PeriodicalId":180557,"journal":{"name":"2016 International Renewable and Sustainable Energy Conference (IRSEC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128221421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
